Storage monitoring with PRTG 

To avoid storage problems or failures negatively impacting your business, make sure you monitor all storage components 24/7 
with a solution that includes all features required for monitoring the entire data storage process.

PRTG keeps monitoring simple, while ensuring performance, clarity and ease of use.



Storage has always been vital for IT


Today, as IT is the basis of almost every company’s business processes, and with digitalization and big data, storage has become critical for every business. Failures can not only have a fatal impact on business success, but even small performance issues can cause serious problems. This applies to a NAS in a small company as well as to huge SANs in enterprise environments.

What is cloud storage?

There is a new dimension of storage becoming more common: Cloud-based storage. Whether it’s simple file sharing using Office 365 or Dropbox, cloud-based content delivery networks (CDN) or big data applications, cloud storage is everywhere. And the principle remains the same: you want to ensure you don’t lose your cloud-stored data.


Storage issues cause business problems

Many aspects of your business can be affected by storage issues. Let’s look at some typical scenarios:

Data loss through hardware failures

Even smaller storage systems today have multiple layers of redundancy based on RAID levels and multiple disks. Nevertheless, failures happen, and cooling failures can lead to synchronous destruction of multiple disks and to irreversible loss of data. In larger storage systems, which can handle the loss of multiple disks without urgent problems, such failures cause performance issues and can lead to data loss on a long-term basis. Faulty hardware must be replaced in time to assure maximum performance and reliability for the entire system.

Data loss through software issues

The availability and performance of modern storage systems depend mainly on software components, while the hardware is often redundant. Although it’s generally easy to discover hardware failures, it’s much more complicated to recognize data loss due to software problems. Modern storage systems from vendors like Lenovo, QNAP, Dell, or NetApp are complex applications consisting of many components and layers. Small errors could remain undetected until they have become critical failures that cause massive data loss.

Not only storage systems have impact on data integrity: backup software, databases, and, of course, virtual infrastructures play a vital role on the software side of data storage.

Business impact of performance issues

Critical issues are not only caused by data loss based on hardware or software failures. Even small disturbances of a storage system can have a massive impact on overall business performance. Critical business processes could slow down because data is not available or can’t be stored in time. As a consequence, a purchasing process in a web shop might fail, a backup process might be interrupted and thus corrupted, or a security update might fail and leave open vulnerabilities (just to name a few examples).


Secure your business by monitoring your storage with PRTG

To avoid negative business impact due to storage problems or failures, all storage components must be monitored, 24/7.
This means monitoring hardware as well as software, and availability as well as performance.

Of course, most components of modern data storage have their own monitoring system included.
But, looking at the above list of critical components, it quickly becomes clear that one central monitoring solution
is required to get the entire storage system with all its elements and tools in one central overview.
This solution has to fulfil some main requirements: 

Monitoring of hardware

Quite clear and easy: The system must be able to monitor the status of a physical disk, as well as its temperature, fan status, CPU etc.

Monitoring of storage systems

Dell EMC, NetApp, Lenovo – a monitoring system should offer out-of-the-box support for the most common storage vendors, and also include the flexibility of creating custom integrations for other systems quickly and easily.

Monitoring of IT infrastructure and performance

Switches, firewalls, servers, databases, virtual hosts and many other IT components play a vital role within the entire data storage process. A holistic monitoring solution should also include features for a general overview about your entire IT.

Monitoring of cloud storage 

As mentioned above, storing data in the cloud is vital. The monitoring solution should also give insights into the most common cloud storage providers.

PRTG Network Monitor: Storage monitoring and more

With PRTG, Paessler offers a comprehensive monitoring solution including all features
required for monitoring the entire data storage process.


 Dedicated storage monitoring

PRTG includes a wide range of predefined sensors (monitoring entities) for monitoring the most common storage systems like Dell EMC, NetApp, HP, Lenovo, Synology, QNAP or even a Buffalo TeraStation™. This also includes sensors for monitoring physical and logical disks for those systems. For cloud storage, PRTG has out-of-the-box sensors for services like Google Drive, Amazon Web Services, Microsoft OneDrive or Dropbox.

See the full sensor list


Hardware and IT monitoring

PRTG includes native sensors for almost every hardware and software component in classic IT environments. From switches, servers, CPUs and fans to databases, backup-tools and virtual hosts. It can monitor availability of those components as well as performance and traffic using all common monitoring protocols.


More than just storage monitoring

PRTG can monitor the entire path data takes from the source application to the final disk, folder or database that it is being stored on or in. All features, from traffic monitoring to server, hardware, database or virtual monitoring, as well as monitoring of actual storage devices and applications, are included in every license of PRTG.


PRTG alert system

With PRTG, you can define thresholds to warn you before an outage occurs. You decide how to receive such alerts: Via email, SMS, push notification, or otherwise. The notification feature provides huge value for those on call – they will immediately see where the issue lies, and if the issue has been acknowledged by the responsible party.
